Built for highly aerobic alpine activities, the Centrifuge Jacket features wind- and weather-resistant hard-faced fleece on the chest and front torso, but highly air-permeable Radiant LT Fleece on the back, side, underarms and face panel. This combination of fabrics allows the Centrifuge to protect from inclement weather while remaining ultra-breathable. Also featuring an alpine cut and a close-fitting balaclava-style hood, the Centrifuge is the ideal layer for traveling fast and light in less-than-ideal conditions.c
